Anthea

At 34,885 gross tons, Anthea is the 16,365th largest of the 84,014 vessels in this registry that report a tonnage. The median across that set is 5,994 GT, so this hull is about 5.8 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 6,242 general cargos held here, it ranks 58th by tonnage — larger than 99% of that group. Their median tonnage is 2,963 GT, and the largest tenth begin at 10,970 GT. The flag most often flown by this group is Panama (565 ships). The yard that appears most often against it is Cestné a Stavebné Mechanizmy Tisovec, with 137 hulls on record.

Anthea was built in 1997, making it 29 years old. It is one of 1,319 hulls in this registry delivered that year, a cohort whose median tonnage is 8,388 GT; within it this ship is the 250th largest. Across the whole of the 1990s the registry holds 12,006 vessels, median 4,956 GT. The median build year across the entire registry is 1995.

The registry attributes 186 vessels to Jiangnan Shipyard, with a median tonnage of 36,438 GT, delivered between 1973 and 2025. See the rest of that yard’s output.

At 196.3 m overall, Anthea is 95.3 m longer than the 101.0 m median for general cargos on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9112973 this registry holds 62 other vessels, whose median build year is 1996 and which range from 1994 to 2002. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1997.

Its IMO number, 9112973, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 1×5 + 2×4 + 9×3 + 7×2 = 123 — and the last digit of that total, 3, must equal the seventh digit, 3. It does, so this number is well formed.
